Diagnostic Yield of Bronchoscopy with C-Arm Scopy in Cases without Endobronchial Lesion

WOS: 000376567100007Aim: Fiberoptic bronchoscopy (FOB) is widely used in the diagnosis and treatment of pulmonary diseases. FOB sensitivity is generally low in tumors localized in the outer third of the lung. Diagnosis of peripheral pulmonary lesions can be difficult; however, the use of computed tomography (CT)-, fluoroscopy- or ultrasonography (USG)-guided surgery increases the diagnostic rates. In this study we aimed to compare the diagnostic values of C-arm fluoroscopy-guided bronchoscopic lavage, brushing, and biopsy samples obtained in cases where radiological masses or parenchymal lesions were detected, but endobronchial pathology was not found. Material and Method: In this prospective observational study, bronchoscopy was performed to the patients who had a mass lesion or parenchymal infiltration on chest radiogram and who had no endobronchial lesion, the diagnostic results of the bronchoscopic lavage, brush and biopsy specimens have been compared where C-arm scopy guided the procedures. Results: 60 patients (45 male) with a mean age 61.5 +/- 9.6 were enrolled into the study. The lesions were mostly located in the right upper lobe. 45 patients had peripheral mass lesion, 17 patients had noduler lesion where consolidation or infiltration were present in 18 patients. The diagnostic yield of the bronchoscopic biopsy was 36%, brushing 20% and 21% for the bronchoscopic lavage. Overall diagnostic yield with all bronchoscopic methods was 45%.
